or masonry wall, andthe chief` Iobject Vof the s inventionlis to provide an anchor for the threaded'en'ds -of :brackets for the supporty of electric cables, .wires and other"appliances,l

Another object isto produce: a device Vof the. character `set` forth which is adaptedr :foruse more particularly in ]o1nts in stone or brickwork.

A still further object is to provide an anchor of simple, strong, durable, ellicient andfincxpensive. construction; and in order that it may be fully understood, reference is to be had to the accompanying drawing, in Which:-

Figure l is a top plan View of an anchor device embodying the invention;

Figure 2 is an end view of the same;

Figure 3 is a central vertical section through the device as it appears in Figure l;

Figure 4 is a section on the line lV-IV of Figure 3;

Figure 5 is a perspective view of one of the members of the device; and

Figure 6 is a view of a wall and shows applied thereto a pair of the anchor devices.

Referring now tothe drawing in detail, in which like reference characters identify corresponding parts in all of the figures, l indicates a relatively concave member tapering from one end to the other and formed at its side margins with downwardly bent wings 2 for the purpose which will hereinafter appear. Adjacent each end and at opposite sides of the longitudinal center of the device are tongues 3 and diametrically opposite each of said tongues is a slot l, said tongues and slots being cut out of the wings 2 where the latter join the body of the member 1, in such a manner that when a pair of the devices are placed in abutting relation to provide a tapered passage, the tongues and slots of the two members will interlock and reliably hold the members against longitudinal movement or side slip with respect to each other.

The side wings 2 are split as at to make them more flexible in order that when inserted in position, as will hereinafter appear, such wings may more readily adapt themselves to the irregularities of the cavity in which the anchor device is fitted.

The larger ends of t-he concave channels SPLT ANCE-03. SGCKET.

tion fromv such injury or distortion would" make it difficult to :prop screws or the like.

When in yuse an irregular shaped opening H is first drilled in the wall by the use of any suitable tool, preferably in the case of a masonry wall in the mortar. A pair the devices with their tongues and slots intei-locked is now forced by hammering, if

erlv insert wood necessary, into the Opening, and during'this operation the wings 2 will be bent toV conform to the irregularities in the walls of the cavity, the splits 5 allowing the w. to more readily adapt themselves to the openings and at the same time offer addif tional resistance to the withdrawal of the device. lt will be understood, in this connectiom that the device is preferably made of a light and thin metal. V

rlhe threaded end of a screw (not shown) or the like, is now engaged with the threaded bore 6 of the anchor, and it will be ev' that as the screw is screwed into posi the members l will be forced apart due to their tapering construction, and the wings 2 will be forced to conform to the irreg` il r walls of the cavity and the device w.' l be permanently and rigidly locked in position.

lt will be apparent that the anchor will be held in position upon the removal of a screw, and that, therefore, the anchor is permanent in character. lt is also desirable to point out that the members forming each hor are duplicates in construction. leading to a saving in manufacturing costs and also in costs of installation, as the worker will not be compelled to make sure that he has cooperating members before preparing to insert an anchor in the wall.

From the above description it will be apparent that l have produced a device of the character described, which possesses all of the features of advantage set forth as dcsirable, and while I have described and claimed the preferred embodiment of the same, I reserve the right to make all changes properly falling Within the spirit and scope of the appended claims.

I claim:

l. A device of the character described comprising a tapering socket composed of a pair of like members having adjacent diverging longitudinal Wings; each member having diametrically opposite tongues and slots7 the tongues of each member engaging the slots of the other member.

2. A device of the character described comprising a tapering socket Composed of a pair of like members having adjacent diverging longitudinal Wings, each Wing being transversely split; each member having diametrically opposite tongues and slots, the tongues of each member engaging the slots of the other member.

3. A device of'the character described comprising a tapering socket terminating at its small end in a driving point composed of a pair of like members having interengaging elements to allow movement of said members toward and from each other Without dislocation of such members, and a plurality of pliable Wings carried by each of said members and projecting radially outward therefrom.

4. A device of the character described comprising a tapering socket composed of a pair of like members7 the small end of said socket constituting a driving point, and each member of the socket having diverging longitudinal Wings adapted for bending upon forcing the socket into position.

5. A device of the character described comprising a tapering socket terminating at its smaller end in a driving` point. composed of a pair of like members, and a plurality of pliable Wings carried by said members and projecting radially outward therefrom.

In Witness whereof I hereunto ai'lix my signature.

HARRY L. JOHNSON.
